Spills on the stovetop can be easily cleaned if sprinkled with salt first. The salt acts as an absorbent, plus it has a mild abrasive quality that won't harm the surface. If you've spilled something into your burner pans on your electric stove, sprinkle the spill with salt and cinnamon, and wipe away. The cinnamon will mask the burned-on smell the next time you use the burner.
All stovetops, even ceramic glass ones, can be cleaned easily with a baking soda solution. Use a toothbrush dipped in baking soda to get into any tight corners. Then rinse everything very thoroughly to avoid leaving a white residue.
